How to Avoid including relationships of relationship

[ritesh2741]

I wanted to avoid including the relationships while including relationship. How can I achieve that? For Example,

class MovieSerializer
  include FastJsonapi::ObjectSerializer
  attributes :name, :year
  has_many :actors
  belongs_to :owner
  belongs_to :movie_type
end

class ActorSerializer
  include FastJsonapi::ObjectSerializer
  attributes :name, :rating
  belongs_to :movie
end

options = {:include=>[:movie]} ActorSerializer.new(Actor.first,options).serializable_hash gives me

{  
   "data":{  
      "id":"1",
      "type":"actor",
      "attributes":{  
         "name":"Robin",
         "rating":5
      },
      "relationships":{  
         "movie":{  
            "data":{  
               "id":"1",
               "type":"movie"
            }
         }
      }
   },
   "included":[  
      {  
         "id":null,
         "type":"movie",
         "attributes":{  
            "name":null,
            "year":null
         },
         "relationships":{  
            "actors":{  
               "data":[ ]
            },
            "owner":{  
               "data":null
            },
            "movie_type":{  
               "data":null
            }
         }
      }
   ]
}

Question is How can I avoid, the relationship portion

"relationships":{ "actors":{  "data":[ ] }, "owner":{ "data":null }, "movie_type":{ "data":null }} 

that comes along with the included movie. I need the relationship while serializing movie but not while serializing actors.
